NARROW-WARE LOOM.

Specification of Letters Patent No. 28,135, dated May 1, 1860.

To 'all whom 'it may concern:

Be it known that I, AARON IVILLIAMSON, of the city, county, and State ofNew York, have invented a new and useful Improvement in Looms; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, forming part of this specification, in which- Figure 1, is afront view of the lay, shuttle driver and shuttles of a hand loom withmy improvements. Fig 2, is a horizontal section of the same in the planeindicated by the line af, ai, in Fig. l. Fig. 3, is a transversevertical section of the same in the plane indicated by the line y, y,Fig. 1. Fig. 4E, is a transverse section of the raceway exhibiting amodification of my invention. Fig. 5, is a transverse vertical sectionof the shuttle-driver detached from the loom.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention relates to that description of loom known as thenarrow-ware loom, employed in weaving tapes and other narrow fabrics. Inthese looms it is well known that several webs are woven at the sametime..

.The object of my invention is to weave articles or fabrics composed ofa series of narrow webs united together at intervals by a fillingrunning through the whole series, such as horse-nets and skeletonskirts, and to this end the nature of my improvement consists in acertain construction of the raceway of such looms to provide for theintroduction of a filling which will extend through the whole or anyportion of the series of narrow webs.

To enable others to make and use my invention, I will proceed todescribe its construction and operation.

A, A, are the swords, B, is the rocker, and C, C, the longitudinalpieces of the lay. D, is the reed tted to the lay in the usual manner.

E, E, is the board which constitutes the lower part of the raceway,having a number of openings a, a, corresponding with the number of websto be woven, to permit the webs to pass through. This board is preciselylike the lower board of the raceway of the tape or narrow-ware loomsheretofore in common use, and secured in the same way b v bolts 7', f,to the lower longitudinal piece c, of the lay; and its upper edge fitsin the usual manner to a groove d, in the bottom of each of the shuttlesF. The corresponding upper board which has been hitherto commonlyemployed to constitute the upper portion of the raceway and which coversup the front of the reed except where there are openings like those a,a, in the lower board for the webs to pass through, and thus preventsthe introduction of a filling extending through or across the wholeseries of narrow webs, is dispensed with, and in place thereof I use ametal plate G, G, either in the form vrepresented in Figs. 1, 2, 3, orthat represented in Fig. 4. I -will first describe that represented inFigs. 1, 2 and 3. This plate is secured to the lower longitudinal pieceC', of the lay at the back of the board E, E, and its upper part is bentforward at a right angle as shown at Z, b, to extend over the tops ofthe shuttles F, F, and a tongue c,` is formed along the under side ofthe front edge to constitute an upper guide, to enter the groove cl',commonly provided in the top of each shuttle. This plate it will be seenby reference to Fig. 3, leaves an unobstructed opening clear across theloom, in front of the reed to permit the introduction of the continuousfillings which are to connect the narrow webs, to be introduced at therequisite distances apart, as the weaving proceeds, and the part ZJ,serves as a resting place for the said filling as is illustrated in thesaid figure by the representation of the lling in red outline. The plateG, Gr, shown in Fig. 4, is applied in the same manner at the back of theboard E, E, but instead of being extended high enough to reach over thetops of the shuttles F, F, it is only extended to about the middle ofthe backs of the shuttles and provided with a tongue g, extending alongits front to enter a groove 71 in the back of the shuttle. This form ofthe plate leaves a similar unobstructed opening above the shuttles andin frontof the reed, clear across the loom, to that left by the firstdescribed plate, and is in all respects equivalent thereto so far as itconstitutes an upper guide for the shuttles, but it is not so welladapted for application to looms already Constructed with a top board,as it necessitates the alteration of the shuttles which the firstdescribed plate does not.

The shuttle driver employed in connection with this improvedconstruction of the raceway is substantially like that employed in othernarrow ware looms in all but one particular. It consists of a frame H,H, I, I, sliding longitudinally in guides z', i, attached to the frontof the lay and furnished with driving pins j, j, standing up between theshuttles. The ends I, I, of this frame are thrown back from the upperand lower parts `H, H, in the manner represented in Figs. 2

and 5, as far as the face of the reed so as to prevent them offering anyobstruction to the continuous fillings which are thus enabled to beplaced in the loom in front of the said portions I, I.

In applying this invention, the warp for each tape or narrow web shouldbe divided into two equal parts, each requiring a cornplete harness, andthe harness is so mounted that each half of the warp for every tape orweb can be woven separately to weave the tapes or narrow webs singlebetween those parts. At starting, the whole of the harness is set inoperation at once, to weave the tapes or narrow webs single for acertain length, then one half of each warp is woven to a length equal tothe width or semidiameter of the continuous filling, and then the otherhalf of each in the same manner. The continuous connecting illing isthen laid in between them in front of the reed by hand or by anyconvenient means and the whole of the harness set in operation. Thefirst shot of filling in the several tapes or narrow webs then securesthe continuous connecting filling, and the weaving of single narrowtapes or webs then proceeds with for the length desired between thecontinuous connecting filling', when one half the harness is thrown outof operation, and first one half and then the other half operatedseparately to make the narrow webs double for asutlicient length toreceive and contain another continuous connecting filling which isinserted as before, and then the weaving of the whole of each of theseveral warps is again proceeded with till the Ydistance for putting inanother continuous connecting filling is arrived at, and so on for anylength.

If desired, ythe shuttle race may be completely inverted, that is tosay, the plate Gr, be made to take the place of the lower boardheretofore employed instead of that of the upper one, and the upperboard retained in its usual place.

Wha-t I claim as my invention and desire to secure by Letters Patent,is-

Constructing one portion of the raceway of a tongued plate G, appliedsubstantially as described, to constitute a guide which leaves acontinuous unobstructed opening in front of the reed, clear across theloom, substantially as andfor the purpose herein described.
